Genetic researchers use fruit flies as a model organism in their research because of the diversity of different traits available to study (e.g. body length, eye color, number of bristles, etc.). One such researcher is investigating the typical number of bristles found on the abdomen of fruit flies. He collects a simple random sample of 57 flies from a wildtype population. The mean number of bristles for his sample is 8.5 (standard deviation is 3.4). If the researcher uses a...
